The pseudo-equilibrium concentrations of the H+, IO3-, and H2OI+ ions, kinetically very important species in the disproportionation reaction of iodous acid, have been determined from the equilibrium dissociation reactions of sulfuric and iodous acids in the quasi-stationary state. The values observed were higher than the concentration of the protonated ion of hypoiodous acid.restrictedAccessarticle10.1007/s11164-013-1273-22-s2.0-84923701784
